[Abstract]:In order to improve the reliability of the carrier communication system, a high reliability carrier routing algorithm is proposed in this paper. In this paper, a high reliability carrier routing algorithm is proposed. The algorithm takes the bit error rate as the reliability measure, and first analyzes the mechanism of the line environment and the signal noise ratio of the equipment to the low voltage carrier communication error rate. In order to reduce redundant forwarding nodes and save network resources, this paper proposes a minimal connected dominating set routing algorithm applied to low voltage power line carrier routing in order to reduce redundant forwarding nodes and save network resources. This paper selects the carrier platform area of 50 nodes to carry out experiments and experiments. The results show that, compared with the cluster routing algorithm, in the BPSK modulation mode, the algorithm reduces the bit error rate by 14.9% and above, and realizes the reliable networking of the low voltage power line carrier communication network of different scale regions.
